WHY At home, light pees can happen in the same bathroom multiple times. Each flush uses 1.6-7 gallons of water*. We will reduce water waste by not flushing every time. *That's, on average, more than an ice bucket's worth of water.
HOW Try using the same bathroom and flushing every other time (only for #1, of course!). If we won't be home for a while, make sure to flush before leaving.
